I have no faith in the Wagos for anything beyond a fluorescent ballast replacement or similar very low load.
I just tore one apart that was sitting on my desk.
There is only about 3/16" of contact surface on just one side of the conductor, and the other side is held in by spring pressure in the same manner as a "back-stab-in" receptacle.
The contact surface is apparently aluminum, and the spring seems to be stainless steel.
Maybe it's just me, but I don't feel this is a sufficient connection.
